Astronaut Cap

The astronomers then conducted an analysis called a Bouger correction in order to subtract the gravitational effect of topological features, such as valleys and mountains, from the total gravity field. What is then left is the gravity field hidden beneath the lunar surface, existing within its crust. Many people listen to the weather report on the radio before they head out the door in the morning so they can be prepared for the day to come. Additional modeling showed that the strange features must be atmospheric--but nevertheless close to Titan's surface--probably creating a very thin layer of tiny solid organic particles. Because they are located directly above the dune fields surrounding Titan's equator, the only possible explanation left is that these mysterious spots are really clouds of dust churned up from the dunes.
